Young Rampart Crater

This image captures the western side of a relatively young “rampart” crater in theTharsis region. Rampart craters are surrounded by a !uidized ejecta blanket (an ejectablanket is the material thrown out around a crater when the impact occurs, in this caseresembling the whites of a fried egg, where the crater is the yolk). Researchers speculatethat these may form when an object impacts ground that contains !uid (liquid orfrozen) that is released upon impact.
